OpenShift Projects Explained¶

Introduction¶

OpenShift projects are Kubernetes namespaces with additional project metadata and access workflows. Use projects to isolate teams, quotas, role bindings, and application resources.

Why This Matters¶

OpenShift adds security defaults such as SCCs, project isolation, and integrated OAuth/RBAC behavior. These protections are useful only when permissions are granted narrowly and verified.

Step-by-Step Configuration¶

oc project app

oc get pods -n app

oc get events -n app --sort-by=.lastTimestamp

oc describe pod web-7c9d7f6f8b-jx4mk -n app

Example output:

Now using project "app-dev" on server "https://api.ocp.example.com:6443".

NAME       DISPLAY NAME   STATUS
app-dev                   Active

Verification¶

oc get project app-dev

oc auth can-i create pods -n app-dev

oc get resourcequota -n app-dev

Security Best Practices¶

Grant the smallest role or SCC that works, prefer service-account-specific access, keep secrets out of Git, and verify permissions with oc auth can-i.

Common Mistakes¶

• Looking only at the final error and ignoring events.
• Checking the wrong project with oc.
• Changing several objects at once before confirming the current state.

Troubleshooting¶

Compare the failing user or service account with the role binding, SCC admission error, project quota, or OAuth status shown in OpenShift events.
